kube-controller-demo's Issues

uses patch() instead of update()

It's possible that new versions of kubernetes introduce new fields in objects (e.g. "taints" on node objects in v1.6). If we use update() rather than patch() we possibly will clear these fields inadvertently if our client-go is not up-to-date enough to know about the new fields.

Hi Aaron,
What software license is this code released under?

"make all" does not work

I installed go 1.8.3 into $HOME/go, added this to my .bashrc:

export GOROOT=$HOME/go
export PATH=$PATH:$GOROOT/bin

cloned the repo and make all gives me:

mkdir -p bin/linux/
GOOS=linux GOARCH=amd64 go build -ldflags "-X github.com/aaronlevy/kube-controller-demo/common.Version=b1ef16ef4d572ea4496502d0520c64e2565e068f" -o bin/linux/r

testing example?

Hi Aaron!

I really enjoyed your presentation last week at KubeCon. I played around with this controller demo, and I was wondering what your take is on how to test a controller?

Is the best way to mock out the events? If so, how do you mock them?

Cheers!

Make all is not working

when i run make clean all i get this

rm -rf bin

deepcopy-gen

I am trying to adapt this example by adding my own Custom Resource Type. When I change the name of the resource type from Example I get Deepcopy not supported errors. I think that I am supposed to run deepcopy-gen on the package - but it is unclear how to do so.
